Please note, the installation instructions on the packaging are in English and perfectible - as well as patterns. Personally I wasted a game on three of these protections. Be aware that each protection is composed of three elements: the protective film, adhesive front and rear. The first adhesive to withdraw partially and gradually and carefully during application on the iPhone, the second adhesive (outside) to remove finished. Of course in the installation, always try to smooth to remove bubbles from the inside to the outside. In the end, very satisfactory result despite some bubbles residues (2 in my operation) and protective film practically invisible or at least very discreet.
